This is one of many datasets generated as part of the cited study. It shows Western Conterminous US Killed Trees Per Grid Cell, Western Balsam Bark Beetle, Subalpine Fir, 1998. Below is a description of the entire study: Abstract. Outbreaks of aggressive bark beetle species cause widespread tree mortality, affecting timber production, wildlife habitat, wildfire, forest composition and structure, biogeochemical cycling, and biogeophysical processes. As a result, agencies responsible for forest management in the United States and British Columbia conduct aerial surveys to map these forest disturbances. Here we combined aerial surveys from British Columbia (2001â2010) and the western conterminous United States...

Ducks and other waterfowl in the U.S. are valued and enjoyed by millions of birdwatchers, artists, photographers and citizens for their beauty and appeal. Waterfowl also provide game for hunters throughout the country and act as an important source of revenue for states and local communities. Loss of habitat and migration corridors due to land use changes and changes in climate threaten these birds, however more scientific information is needed to understand these processes. This project used available annual surveys of duck counts, along with data on the location and availability of ponds and temperature and precipitation patterns, to model where across the continental landscape waterfowl were present and if their...

To provide information on what areas have a groupings of dead (red) pine trees which indicate a high likelyhood of green attack mountain pine beetle trees. This data is used to help focus ground survey work and is not 100% accurate. The current beetle year (August 15 to August 15) Mountain Pine Beetle aerial survey red tree locations. This data is used to help focus ground survey work and is not 100% accurate.

This dataset is a compilation of forest insect, disease and abiotic damage mapped by aerial detection surveys on forested areas in the United States. At this time, the National Aerial Survey Data Standards require only mortality and defoliation data be collected and reported. However, many cooperators collect data on other types of damage and therefore, the national database has been designed to accommodate these data. Low-level flights, typically 1,000 to 2,000 feet above ground level, are used to map forest damage. Observers use paper maps, typically 1:100,000 scale USGS maps, upon which they record the damage. There is also a digital sketchmap system that may be used. The digital system uses GPS to display the...
